Claims priority, application Germany Oct. 14, 1955 1 Claim. (Cl. 15-22) effect that cleaning liquid is pressed out from the fabric 2 in a very quick manner and is sucked in again so that the fabric is submitted to a quick periodical flushing with cleaning liquid. Thus a cleaning effect is obtained which depends, besides the number of the exerted strokes also on the intensity of the stroke, i.e. the stroke is the more eflective, the stronger it is. It is evident that the beating treatment is, on the one hand, if it is to be effective, very exacting and time consuming and requires, on the other hand, a very fine sense of touch, for if the beating is too hard the danger of destroying the fabric arises.

The present invention relates also to the removing of stains from fabrics by means of heating with simultaneous treatment wifh a cleaning fluid. One object of the invention is to make the beating treatment less time consuming and exacting and, at the same time, more efiicient than was the case with the devices up to now. The device according to this invention consists of a vibrator, the vibration member of which is arranged in such a way that a suitable tool for the beating treatment, e.g. a ham.- mer, a brush, or the like can be releasably attached and that a container is fixed on the vibrator, which container is connected with the tool support by means of an elastic tube.

Considering the process involved in removing stains by beating by hand it had to be assumed that the beating strokes of a vibrator would in no case be suflicient for the removing of the stains. In fact the process in the vibration treatment of stains is in principle another process than that in the usual known beating treatment. The vibrator executes about fifty beating strokes per second, the effect or" which depends, however, not as in the other devices upon the strength of the stroke applied but is based on the fact that the vibration strokes applied on the fabric create resonance oscillations coming from the surface on which the fabric reposes, which oscillations have a quick loosening effect on the dirt and cause its easy separation from the fabric. The oscillations assist at the same time the effect of the cleaning liquid. In

employing vibration it is not the single beating stroke or 65 ice such as the beating itself and also the treating by means of the cleaning liquid is dispensed with. The danger of the destruction of the fabric by too strong a beating is absolutely eliminated.

In the drawings:

Fig. 1 is an elevation, partly in section, of the device, and

Pig. 2 is a modified form, partly in section of the device, showing a preferred embodiment.

Other and further objects, features and advantages of the invention will be pointed out hereinafter and appear in the appended claim forming part of the application.

As shown in Fig. 1 of the drawing the device consists of a vibrator for producing resonance oscillations 1, and a shaft 2, which are arranged, according to the invention, in such a way, that a suitable tool for the beating treatment, e.g. a brush can be releasably attached. According to the invention as shown in Fig. l, a reservoir 4 for the reception or" the cleaning fluid may be secured to the vibrator 1. To the outlet 5, of the reservoir, is connected a flexible tube 6 or another elastic connection. Because of the flexibility of the connection a transfer of the vibration movements to the reservoir is avoided.

On the free end of the shaft 2 a connecting element 7 is fixed, which serves on the one hand as a holder for the nozzle 8, which can be connected to the flexible tube 6, and on the other hand as an organ for the distribution of the liquid in the heating device, e.g. the brush 3. The connecting element consists in the represented embodiment of a body with a concave lower part, which forms with the heating device on which it is applied, a hollow space 9. The brush 3 is provided with bores 13 in the bottom of the brush, which bores feed the cleaning fluid into the brush from the fluid retaining cavity space 9.

The attachment of the connecting element to the tool support is efifected in the illustrated device as shown in Fig. l by means of a screw 10, the head of which has a bore 11 for screwing in the screw 12 holding the beating tool 3.

For the adjustment of the liquid supply to the heating device it is possible to provide at a suitable location a regulating valve which can be operated by means of a proportioning knob. Instead of a brush other beating devices may be used, e.g. scrapers 14 and 15, of which scraper 14 is provided with several scraping extensions, while scraper 15 has only one single extension.

It is recommendable to arrange the container 4 in a releasable and interchangeable manner on the vibrator. Such an arrangement affords the possibility for the user to interchange containers with diflerent cleaning fluids. This has an advantage in that the same apparatus may be used for the removing of different stains, e.g. ink, oil, color, or the like. Besides it is not necessary to pour out the cleaning fluid and to fill in another liquid which is more suitable for removing a certain stain. In such cases it is easier to interchange one container with a cleaning fluid more suitable for the removing of the stain with another container. A preferred embodiment consists e.g. of providing a bottle screw connection on O the vibrator connected with the flexible tube 6, on which connection a quantity of containers, preferably in bottle form, can be screwed. Preferably in such an embodiment bottle-shaped containers of plastic materials are used which can be compressed, so that any trouble in the supply of the cleaning fluid can be overcome by compressing the said bottles.

In the preferred embodiment of the invention, as shown in Fig. 2, there is secured to the vibrator 1a by means of angle 4a a threaded closure 5b for securing a plastic supply reservoir 16 by means of the latters threaded neck portion 16a. Extending through closure 5b is a tube 4a, which serves to secure one end 6a, of flexible tube 6b to the closure. The other end of the flexible tube 6b is provided with a nozzle 8a adapted for insertion into the holder 7a to which brushes similar to those shown in Fig. 1 may be secured in the manner described in connection with that figure. An angled shaft 2a, having a right angle portion, selves to secure a holder 7a to the vibrator 1a in the manner described in connection with Fig. 1. When the housing is held in horizontal position, the shaft is normal to the fabrics working surface. A valve 17 may be provided in tube 6b to control the amount of fluid passing through said valve.

1 claim:

A device for removing stains from fabrics comprising a motor housing adapted to be gripped by a hand, a motor in said housing, a shaft extending from said housing, said shaft being angled including a right angle portion, whereby when the housing is held in a horizontal position said shaft is normal to the fabrics working surface, means for producing resonance oscillations con necting said shaft with said motor, a head releasably held by the free end of the shaft, the free end of the head presenting a concave fluid retaining cavity, a supply reservoir made of resilient plastic material capable 4 of elastic compression, attached on said housing and in communication with said concave cavity, a brush releasably attached to said head and enclosing said cavity, said brush further including in the backing thereof ports communicating with said cavity, whereby fluid is projected from said container through said ports.
